I want to believe in a third "X-Files" movie but the truth is not out there … yet. At one of the most anticipated panels of San Diego Comic-Con, stars Gillian Anderson, David Duchovny, creator Chris Carter, writers Vince Gilligan ("Breaking Bad") and Howard Gordon ("Homeland") and a gaggle of other show scribes gathered for TV Guide Magazine's 20th Anniversary reunion panel on Thursday.

With a spooky Mulder-appropriate entrance, Duchovny and Anderson entered the panel in darkness, shining flashlights around as they made their way to the rest of the awaiting panelists and moderator Michael Schneider from “TV Guide Magazine.” And yeah, fans screamed – a lot. Much like they screamed a lot when “The X-Files” theme song played or favorite episodes or characters were name checked or questions of future reunions (or movies) were asked. In fact, seeing the band back together was enough to keep ‘Files’ philes in a constant state of fan euphoria.
Of course, the dosage of euphoria kicked up anytime sex between Mulder and Scully was mentioned, and it was mentioned frequently. Anderson, who had promised to behave herself, joked the two characters must have had sex since they had a baby, and there was a sex scene “somewhere” out that had been shot but never aired.

When a fan asked what Mulder and Scully would do on a date, she answered “Have sex” and Duchovyny followed up with, "Then maybe dinner?” “I think barbecue," Carter then contributed.

Carter also said he created Scully as his fantasy woman and made her strong, opinionated, tough, and intellectual for that reason, and wanted her to have a complex nature of someone raised with religion but a person of science. He added Mulder and Scully probably fell in love when she first met him in his basement office. This generated a collective “awww” from the audience.

Anderson also waxed sentimental when she said, "I didn't realize Mulder was so cool until a few years later, and then I thought, 'Damn, I should have gotten there sooner.”

Actually, it was pretty noteworthy just how much flirtatious chemistry Duchovny and Anderson continue to share. They would tease each other a little and, at one point, Duchovny told her, "don't give me that look."

Other highlights included Gilligan giving credit to “The X-Files” for helping him create “Breaking Bad.” He said he was a fan of the show “by the end of the first commercial break” before he even worked on it, and that he learned everything he knows from seven years on it. And he even met Bryan Cranston of “Breaking Bad” while filming the sixth season episode “Drive.”

“There'd be no ‘Breaking Bad' without 'The X-Files’,” he said matter-of-factly.

So about that movie? Anderson recently returned to television with a recurring role on “Hannibal,” and Duchovny is still doing duty on “Californication,” but they both said they’d return for a third film – but not a miniseries.

Said Duchovny, "I always thought whenever we can come back together, we would as much as we can, so we will.”

But he added he couldn’t see himself acting alongside Anderson outside of her role as Scully because, "I've always felt like there was something so special about Mulder and Scully."

"I love Gillian … It would have to be something I can't think of to cross that line."

Carter never confirmed whether he’d return for another movie, but he praised Joe Harris’ Season 10 “X-Files” comic, then delivered this major tease:

"You need a reason to get excited about going and doing it again because it's hard work, but this is very inspirational."

Before the panel wrapped, Anderson began a minor bidding war for an autographed cardboard standee of Mulder and Scully. She said it was for charity but Duchovny joked it was “how we're going to get the movie made."
